Bloomberg: Researchers found that foods high in omega-3 do not reduce the risk of heart disease.

The analysis of 72 previous studies showed insufficient support for nutritional recommendations by groups such as the American Heart Association that advocate high consumption of polyunsaturated fats like omega-3 and omega-6, which is found in corn and sunflower oils, as well as some nuts and seeds.

“The current guidelines should reflect the most recent evidence that show that their apparent benefit for reducing coronary risk is potentially low,” Rajiv Chowdhury, the lead study author and a cardiovascular epidemiologist in the Department of Public Health and Primary Care at the University of Cambridge in the U.K., said in an e-mail.
